how will you know its bad?anything i can to check it? i know the current turbo thats in my car is its 2nd turbo. it was installed at toyota dealership in early 2000's. i have the reciept, and its a reman.

Sorry, it's turbo jargon = center housing rotating assembly

It's the part of the turbo that isn't the compressor or the turbine:

hmmm suspect. thats awefully white smoke. did you do a cylinder leak down test? check it out
